Yongte is professional manufacturer for WPC Door Production Process Machine Factory with turn-key project service and high quality
Raw material procurement: Select high-quality PVC resin, wood powder or wood fiber as the main raw materials. PVC resin usually selects medical-grade domestic brand products, and wood powder is provided by professional wood companies with high-quality tree species wood powder, and the fineness, moisture content and other indicators are required to meet the production requirements.
Wood powder needs to be graded, screened, ground, dried, and coated to ensure its quality and performance in subsequent processing. At the same time, auxiliary materials such as stabilizers, foaming agents, modifiers, lubricants, colorants, etc. are prepared in a certain proportion.
Ingredients: According to the product performance requirements and formula, accurately weigh various raw materials and add them to the mixing equipment.
Put the weighed PVC resin, wood powder, stabilizer, foaming agent, modifier, etc. into the high-speed mixer for preliminary mixing to make various raw materials evenly dispersed.
Heating and mixing: During the mixing process, the material is heated to plasticize the PVC resin. The temperature is generally controlled at about 100℃-150℃, and the time is about 5-15 minutes. The specific parameters depend on the formula and equipment.
Cooling and discharging: After the mixing is completed, the material is cooled to about 40℃-60℃, and then discharged into the storage bin for standby.
Feeding: The mixed material is conveyed to the hopper of the extruder through an automatic feeding device.
Plasticizing extrusion: The material is subjected to the rotating extrusion and heating of the screw in the barrel of the extruder, and is further plasticized and mixed to form a uniform plastic-wood mixture. The temperature of the extruder is generally controlled at 140℃-185℃, the main engine speed is 7-15r/min, and the feeding speed is 10-15r/min.
Mold forming: The plasticized material passes through the extrusion port of the extruder and enters the pre-designed mold. Under the action of the mold, a continuous blank with the required cross-sectional shape is formed, such as a blank of a door frame, door leaf, etc.
Cooling and shaping
Cooling: The extruded blank immediately enters the cooling device, usually using water cooling or air cooling to quickly cool and solidify the blank and shape it into the required shape and size.
Traction: While cooling, the blank is pulled by the traction device to ensure its continuous and stable extrusion and cooling. The traction speed matches the extrusion speed, generally around 1-5m/min.
Cutting
Fixed-length cutting: After cooling and shaping, the wood-plastic board or profile is cut into the required length using cutting equipment according to the size requirements of the door, such as the vertical frame, horizontal frame of the door frame, and the size of the door leaf.
Trimming cutting: The edges of the cut parts are trimmed to remove burrs, flash, etc., so that the edges of the parts are smooth and flat to ensure the installation and use performance of the door.
Feeding: The mixed material is conveyed to the hopper of the extruder through an automatic feeding device.

Trimming cutting: The edges of the cut parts are trimmed to remove burrs, flash, etc., so that the edges of the parts are smooth and flat to ensure the installation and use performance of the door.
V, Surface treatment:
Sanding: Use a sanding machine to sand the surface of the cut door parts to remove surface defects, improve flatness and roughness, and provide a good foundation for subsequent surface treatment.
Lamination or painting: Thermal transfer technology can be used to transfer various wood grains, colors or patterns to the surface of the door, so that the product has a variety of high-end wood grains and colors; it can also be painted, painted, etc. to increase the beauty and durability of the door. In addition, peritoneal treatment can be performed, and a layer of protective film can be attached to play a waterproof and scratch-proof role.
VI, Assembly WPC doors
Door frame assembly: Assemble the cut door frame parts, usually using mortise and tenon joints, glue joints or connectors to ensure the structural firmness and dimensional accuracy of the door frame.
Door leaf installation: Assemble the door leaf with the door frame, install hardware accessories such as hinges and door locks, debug the opening and closing flexibility of the door, and ensure the normal use function of the door.
VII, Quality inspection of WPC doors:
Carry out quality inspection on the surface treated WPC door leaf and profiles, such as size, appearance, performance, etc., to ensure that they meet relevant standards and requirements.
VIII, Packaging and warehousing: Pack the WPC door profiles that have passed the quality inspection and store them in the warehouse for storage and custody.
